The Siemens 6AG1134-6HB00-2DA1 is a 2-channel analog input module for the ET 200SP distributed I/O system. It handles voltage and current signals across multiple ranges, with 16-bit resolution on the ±10 V range and 16-bit including sign on the ±20 mA range. Oversampling is supported on both channels, and isochronous mode enables time-synchronized acquisition for motion or high-speed processes. The module occupies 15 mm on the DIN rail and requires a BU type A0 or A1 base unit. Supply is 24 V DC with typical power draw of 0.95 W without sensor supply.
Key ratings and what they mean for fit
Resolution across ranges: the 16-bit ±10 V range and the 16-bit ±20 mA range offer the widest dynamic range. For applications needing channel-by-channel wire-break detection, this only works in 4–20 mA mode. Short-circuit detection is available on voltage ranges and current encoder supply. The module can oversample each cycle with up to 16 values per cycle, and firmware is updatable. Diagnostic alarms, limit value alarms, and group error outputs are built-in. A green LED per channel shows status, and a red LED per channel indicates diagnostics.
